Sometimes I fantasize about using self injury in this way, and sometimes I kind of do it.

For example if I feel bad because I feel someone is being unfair to me, I sometimes fantasize about showing my scars, or cutting in front of them to show what they are doing to me, like using self harm to manipulate things to my advantage by making people feel sorry for me and give me what I want. Sometimes I think that I could easily do this, but it wouldn't be "playing fair" to do so, so I don't.

I also fantasize sometimes about getting mugged or something, and then threatening to cut myself in front of the mugger so that they get freaked out and feel bad for what they did.
